    tmac/s.tmac (UX): Drop undocumented support.
    
    * tmac/s.tmac (UX): Drop undocumented support for this macro.  This
      implementation isn't consistent with historical ones, which identified
      the trademark holder.  But doing that is a problem, so just stop
      trying to cope.  Also, spelling Unix in full caps was an imposition by
      the AT&T legal department on on the CSRC.
    
      "The name Unix is a trademark, originally owned by Bell Labs and
      subsequently traded off like a baseball card among a number of
      companies." -- Ben Klemens
